Meanwhile, back at the ranch...
So assuming you've created a table in DynamoDB (either programmatically with Dynasty or manually in the AWS console) we can get an object representing that Table to put items into that table, get items from that table, and perform any other operations on that table.
So let's say we have a DynamoDB table already created called UserData and we want to retrieve an item from it.
var dynasty = require('Dynasty')(credentials),
// Retrieve an instance of the UserData Table
users = dynasty.table('UserData');
Now we can query it:
// This will look in the UserData table, returning the item with a Hash key that
// matches 'victorquinn'
var promise = users.find('victorquinn');
Note, for this library I've chosen to use a Mongo-style syntax here, rather than the DynamoDB names. This is because:
Also note, we're not passing it a callback. We can, but we don't need to because Dynasty has promise support baked in!
Dynasty will also accept a callback function as an optional argument though!
